Malicious fake profiles attacks on Facebook..

Facebook on Thursday fended off an attack in which multiple identical profiles were created to spread malware.

“Clearly, the Data Snatchers have found a way to automate the creation of Facebook accounts, which means they’ve found a way to bypass the Facebook Captcha,”Roger Thompson, chief of research at AVG, wrote in a blog post.
Successfully translating a Captcha, a hard-to-read image of letters supposed to ensure that a human is involved, is required for a new account.

“We’re looking into how these accounts were created, but it’s very likely that the sign-up process was manual, or that the person behind the attack farmed out the Captchas to be solved by humans for a price,”Axten wrote in an e-mail.

For its Captcha system Facebook uses ReCaptcha, “which was recently acquired by Google and is about as well-regarded a Captcha provider as there is,”he said.

When the link in the fake Facebook profiles is clicked a fake alert pops up that tries to convince the user that the computer is infected.
